ls12EcfrrIcA'rion' formingpart of Letters Patent No. 325,747, datenseptember s, 1885.

To. all whom, it may concern: ,y Y

Be it known that I, IsAAo KENDRIOK, of Philadelphia, in the county of.Philadelphia and State of Pennsylvania,` have invented a.

new and valuable Improvement in Apparatus for Burning Gas forIlluminating Purposes; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawing, making a part ofthis specication, and to the letters and gures of reference markedthereon.

The figure of the drawing is a vertical sectional view of my device.

The object of this invention is to secure more perfect combustion,greater economy, and higher illuminating power from the'consumption of agiven quantity ofggas than heretofore attained. To this end I employ, inconnection Vwith a primary lightlgiving burner, a second or auxiliaryheating burner, and means ior supplying heated gas to `the primaryburner, means for supplying gas and air to the auxiliary or heatingburner, means for creating and heating an upward current of air anddirecting the same to the inner surface of the flameof the primary orlightgiving burner, means for outwardly and upwardly deecting the flameand products of combustion of the auxiliary or heating burner, andineans for supplying and directing a current of air to the outer surfaceof the dame of the primary orlight-giving burner at the point ofignition.

The invention consists in the construction and novel arrangement ofdevices, as will be hereinafter more fully set forth and claimed.

In the accompanying drawings, illustrating the devices usually employedin order to carry my invention into effect, the letter A designates achambered gas-light burner, which is preferably of annular form incross-section, having a central opening, B, for the passage of air tothe inner'surface of the dame of this burner, the gas passing to theburner by the pipe or pipes F.

G designates the interior auxiliary non-luminous or heating burner tube,located within the opening B of the main burner and extending upward tothe level of or nearly to the level of the jets of said main burner.This Application tiled August?, 18841. (X0 model.)

heatingtube C is, at its llower end, provided with thejet-inlet candwith air-inlets d. An

4inverted-cone-shaped or cup-shaped detlector,

D, preferably made of porcelain, is located upon a stem or support, z,above theheatertube C, its lower `end or apex being at or near thecenter ofthe annular series of jets b of the main burner. This deleetor,made capable of resistingiujury from high heat, is de-.

signed to direct the flame and products of combustion of the nonluminousburner emitted at the upper end of the burner-tubeG outward and upwardaround said deflector, and, becoming highly heated, to add to thebrilliancy of the flame ot' the main burner.

G represents the glass protector which surrounds themain-burner llameand guards it from lateral currents of air.

H indicates the gas-cock which regulates Vthe supply of gas to the mainburner and to the heatingburner tube. Airinlets e areprovided to admitair to the opening or throat B of the main burner.

The operation is as follows: On opening the gas-supply cock the gasissues through thejet perforations or nipples b of the primary orlight-giving burner A, when it is ignited. Around the lower portion ofthe flame, and

extending downward below the level of the jets b, is the outerdraft-collar, E,whereby air is supplied to the exterior of the maindame. At the same time gas is supplied to the intel rior of theauxiliary or heating burner tube C through the jet or jets c, and air isdrawn into said tube through the inlets d, and together the gas and airissue in a mixed condition from the upper end of the tube C, when it isignited and burned as aheatinggas. The heating flame thus produced is,by means of the detlector D, directed upward and outward around saiddeflector, heating it highly, and'thereby adding greatly to thebrilliancy of the main-burner ame. Air drawn upward through theburner-passage B by the action of the interiorheating-burner is highlyheated, and in this condition is,by the detlector D, directed outwardand upward and brought into close contact with the inner surface of thedame of the main burner. In

this manner it is designed to supply the air in proper condition tofurnish oxygen to the vIO main light-giving iame to secure economy inthe use of gas and to produce a high illuminating power in themain-burner ilame. Y

By means of the interior heating-burner I aiu enabled to dispense withthe ordinary tall chimney or draft-due, because this burner creates asufficiently strong upward draft of air, and at the same time heats it.The operation of this auxiliary burner is automatic or self-regulating.Vhen the full pressure of gas is turned on at the 1ight=burner, acorrespondingly-strong draft of air is maintained by the interior orheating burner, and When the pressure of gas is diminished in the mainburner the action of the auxiliary burner is also decreased, lesseningthe upward draft to the main flame. Y

I do not desire to limit this invention to the precise construction orarrangement of parts herein shown and described, as it is manifest vthatthe same can be varied readily by persons skilled in the art withoutchanging the pri-ir ciples of operation.

I am aware of the Patent No. 250,089, in

which non-lufminous gas is made use of, and

theV same passed lthrough a heater Which is composed of clay 'or'similar material, and

highly heated by jets ofthe non-luminous gas, atmospheric air beingforced through such heater and mingled with the non-luminous gas,issuing in one or more jet-dames againstlime, magnesia, or similarmaterial,to producelight by incandescence, and therefore do not claimsuch devices, broadly.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

In a gas-burner for illuminatingpurposes, the combination, with theannular gas-burner A, having a central opening or passage, B, of theauxiliary or heating burner tube C,itsjet or jets c, and air-inlets d,the cone or cup shaped deiieetor D, arranged so as to have the dame passyon the outside thereof, the draftcollar E, and the regulating-valve H,substantially as-spectied.

I-n testimony that I claim ythe above I have hereuntosubscribed my name:in the presence o't" two witnesses.
